The green data center: Cutting high performance power costs

Since controlling power consumption represents a significant expenditure of time, money, and effort, data center managers need to consider all power reduction solutions at their disposal – from flywheels to eco-mode UPS systems to other efficient alternatives. 

This expert handbook will help guide you through the decision-making process of “greening the data center”. Readers will learn how these methods—along with others—help to provide a smaller footprint while still allowing for higher power density.

  • Cost comparison of power plant architectures for large data centers

    A common practice for large data center applications is to connect generator power plants directly to the electrical distribution network. To make this more cost-effective, it’s suggested that the number of generators running N+1 redundancy is reduced instead of those running 2N. But is this really the best methodology down the road?

    In this whitepaper, get a closer look into what an electrical architecture using an N+1 generator power plant looks like. You’ll also find a series of cost-comparisons to help you get a better understanding of when this strategy becomes the most efficient option for your data center.

  • CW+: Leverage memory technology to cut data centre power consumption

    Within modern data centers, virtualization has become the means of choice when it comes to operating efficient server infrastructures for cloud and enterprise computing. On an individual system level, this translates into a massive increase of DRAM deployments per server. Hence the DRAM’s share in system power consumption and heat generation for non‐persistent memory is much greater than has been known in the past. Leading‐edge DRAM technology offering lower energy consumption and less heat dissipation per Gigabyte should deliver significant benefits at the system and data‐center levels with regards to energy consumption for the computing system (regarded as primary energy consumption) and cooling (secondary energy consumption). Within this project we have analyzed the potential leverage of leading‐edge memory technology in terms of the power savings for overall complete data center. We have selected two identical state of the art server systems with an identical configuration including major components such as power supply, CPU, fan and Hard Disk Drive (HDD) storage.
